SiI 3132
PCI Express to 2-Port Serial ATA II
Host Controller
Building on the proven architecture of Silicon Image’s industry-leading host
controllers, the SiI 3132^™ is a single-chip, one-lane PCI Express to 2-port Serial ATA
(SATA) II host controller that brings server-class features to the desktop.
The x1 PCI Express interface allows the device to connect to the latest mother-
boards that take advantage of this high-speed serial interface. The SiI 3132 also
supports all Serial ATA II features, including 3.0 Gbps SATA II transfer speeds,
Native Command Queuing, port multipliers with FIS-based switching, programmable
output signal swing strengths for longer external cables or extended backplanes,
hot plugging, enclosure management and ATAPI device support.
Users of the SiI 3124 can easily migrate to the SiI 3132 because its driver structure
is similar to that of the SiI 3124. The SiI 3132 offers the best SATA price/performance
and is both flexible and robust for today’s demanding storage applications. When
connectivity to more than two devices is required, a port multiplier device such as
the SiI 3726 can be used with the SiI 3132.
With the SiI 3132, Silicon Image provides customers with drivers for the Windows
and Linux operating systems for both RAID and non-RAID operations. Software
RAID 0 (striping) and RAID 1 (mirroring) functions are supported through
Silicon Image's SATARaid^™ RAID management software utility when each port
is connected to a single hard drive. When used with a SATA port multiplier,
Software RAID 0, RAID 1, RAID 10 (mirrored stripe) and RAID 5 (parity RAID)
are supported.
The SiI 3132 leverages much of the circuit innovation at the physical layer of
Silicon Image’s proprietary reduced overhead Multi-layer Serial Link (MSL^™)
architecture, pioneered and proven through its PanelLink^® products and extended
to the SATALink and Fibre Channel SerDes storage products. MSL technology is a
multi-layer approach to providing cost-effective, multi-gigabit semiconductor
solutions on a single chip for high-bandwidth applications.
